How do I evenly distribute topology?
If you mean maintain a more-or-less even mesh density (and appropriate mesh density), this is something you need to pay attention to throughout the modeling process and adjust for as you go. It's not like you just push a button and make it even. 

If you notice at some point that an area is too dense, dissolving edge loops, sliding edges, and smoothing geometry are some common operations that can help you maintain consistency.
